GEORGE W. BAKER, OF CLEVELAND, OHIO, ASSIGNOR TO THE VHI'IE SEVINGMACHINE COMPANY, OF SAME PLACE.

FEEDING MECHANISM FOR SEWING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 423,111, dated March11, 1890'.

Application tiled August lI 1889. Serial No. 319,468. "(No model.)

To all whom it may concern,.-

Be it known that I, GEORGE WV. BAKER, of Cleveland, in the county ofCuyahoga and State of Ohio, have invented certain new and usefulImprovements in Feed Mechanism for Sewing-Machines and I do herebydeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itpertains to make and use the same. l

My invention relates to improvements in feed mechanism forsewing-machines, the'object being to silnplify the construction andreduce the initial cost.

Vith these objects in view my invention consists in cert-ain features ofconstruction and in combination of parts, hereinafter described, andpointed out in the claim.

Figure 1 is a side elevation of the feed-bar and connected mechanism.Eig. 2 is an end elevation of the same. Fig. 3 is a view in perspectiveembodying my invention, but showing the parts separated.

A represents the cloth-plate of the sewingmachine, and B the feed-bar.To the under edge and near the rear end of the feed-bar is attached anangle-plate c, for engaging cam C, by means of which the feed-bar iselevated and advanced rearward with each revolution of the cam, thefeed-bar being depressed and reversed bythe action of spring c. Midwayof the feed-bar is attached a serrated block or feed proper F, the partsthus far being substantially as heretofore used. The forward end of thefeed-bar is slotted at b, and a block D is nicely fitted to operate inthis slot. BlockD is mounted with an easy fit on spindle E, the latterserving as a fulcrum for the block. Spindle E is journaled iu bosses ca', depending from the cloth-plate, these bosses being pierced laterallyfor the purpose. Boss a is faced off at the outer end and constitutes alateral bearing in one direction for the feed-bar. The lateral bearingfor the other side of the feed-bar is furnished by lateral cam e, thelatter being rigidly secured to the outer end of spindle E. Cn the otherend of the spindle and outside of boss c is mounted thumb-wheel E', formanipulating the feed. With such construction it will be seen thatspindle E by means of cam e and wheel E is held endwise, cam e holdingthe feed-bar and block `D in position bearing against boss a., thefeed-bar sliding on block D and the latter rocking on spindle E, bothfeed-bar and block having an easy [it between the opposing cam and boss.Cam e engages stop G of the feed-bar, the stop being preferably of feltor other soft material that will cause but little noise, the stop beingsecured to the feed-bar by means of screw g and washer g. Cam e is ofthe volute variety shown and usually has about the same throw as cam Caforesaid, with the arrangement of parts such that with the point e ofcam e engaging stop G the feed-bar is thereby held so far rearward thatcam C can give but little end movement to the feed-bar, and,consequently, in such position the feed is reduced to a minimum. Whencam e is reversed by manipulating wheel E until the heel e2 of the camis opposite stop G, .a maximum feed is had.

Heretofore it`was considered necessary to provide a cap or somemechanism to hold the forward end of the feed-bar at least in onedirection laterally; but with my improved construction no cap or extrapiece or pieces is necessary for such purpose, and consequently themechanism to such extent is simpliied and reduced in initial cost.

The combination with stitch regulating shaft and cam, boss dependingfrom the clothplate for supporting the shaft, slotted feedbar carrying astop, and fulcrum-block located in the slot in the feed-bar, such blockbeing mounted on the shaft, the block and slotted section of thefeed-bar being between the said cam and boss and abutting both,substantially as set forth.

In testimony whereof I sign this specification, in the presence of twowitnesses, this 15th day of June, 1889.

' GEORGE W. BAKER.
